JAMES BARBIE CAVERS, OF NEW YORK, N. Y.

COLLAR OR CUFF BUTTON.

SPECIFICATION forming part of Letters Patent No. 637,233, dated November 21, 1899.

Application filedMay 19 1899. Serial No. 717,391. (No model.)

To all whom it may concern: 7

Be it known that I, J AMES BARBIE CAvERs, a subject of the Queen of Great Britain, residing at New York, (W'estchesten) in the county of New York and State of New York, have invented certain new and useful Improvements in Collar and Cuff Buttons; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to collar and end buttons, and more particularly to that class in which are combined a telescopic shank, a base, and a head hinged to one of the parts of the telescopic shank; and it has for its object the production of a simple, durable, and inexpensive device of this character.

With this object in view the invention consists in certain features of construction and combination of parts, which will be hereinafter fully described and claimed.

In the drawings, Figure l is a longitudinal sectional View of my improved button, showing, on an enlarged scale, the parts and the position they assume when the button is in use. sition the parts assume when the head of the button has been swung down for the purpose of inserting the head through or removing it from the buttonhole.

Like characters of reference indicate like parts in both views.

1 denotes the shoeof the button, 2 the head, and 3 the shank. The shank is composed of two sections, the tubular section a and the section b, which is adapted to slide within The open end of the section a is provided with an annular inwardly-projecting stop-flange 4. The section b is hinged to the head 2 of the button in a manner common to this class of inventions and is provided at one end with a stop-shoulder 5, coacting with stop-flange 4, and on the opposite side with a stop toe or lug 6.

7 denotes a V- shaped spring located within the tubular section a and having one end engaging the stop-fiange at and its apex projecting within the path of movement of the stoptoe 6. This spring not only serves to prevent the section b being too far withdrawn from the section a, but also exerts its energy Fig. 2 is a similar view showing the po to force the stop 5 0f the section 1) into engagement with the annular flange 4 of the section a of the shank and hold the button in a contracted position, as shown in Fig. 1. It is wholly immaterial whether the spring be connected to the tubular stem or not. As shown in the drawings, it is not connected and it need not be, for the reason that it cannot possibly get out of place and will perform its function as well at one end as at the other of the tubular section.

When it is desired to remove the button, the part section b is forced outward by-applying pressure to the edge of the head 2 to free the stop 5 from the flange 4 and permit of the withdrawal ofthe section b. This withdrawalis limited by the toe 6, abutting against the apex of the spring 7. After the parts have been withdrawn, as shown in Fig. 2, the head may be swung to bring it substantially parallel with the shank, and in swinging it it will not come in contact with the collar or cuff, thus rendering it less diflicult to withdraw the head from the buttonhole and pre= venting it soiling the cuff about the buttonhole as well as tearing the same.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of the device will be readily apparent without requiring an extended explanation. It will be seen that by the employment of a device of this character after the head has been inserted through the buttonholes of the garments which are to be secured together the shank may be compressed to its smallest length, so that the head and shoe will firmly engage the garments, and thus prevent the shoe from pinching the flesh, as is common in buttons having long shanks.

Changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described the invention, what is claimed, and desired to be secured by Let ters'Patent, is-

A button composed of a shoe, a head and a telescopic shank, the shank consisting of two sections one arranged to slide within the other, and one section being provided at its too the other section and hold the button in a contracted position, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set 15 my hand in presence of two subscribing witnesses.

JAMES BARRIE CAVERS.
